    If you're not keen to turn your garage into a lab, try coplanting in the garden. Studies have shown that wine cap mushrooms, for example, can boost corn's ability to produce delicious ears. These mushrooms are prolific decomposers, they digest organic matter in the soil, and this adds nutrients to the system that the hungry corn eagerly convert into sweet kernels. To start companion planting with fungi, add woodchips and mushroom spawn to your soil. This can be purchased online. Wine caps, and other tasty species like the phoenix oyster mushroom, can be grown this way.
